A thread on the Diablo III forums has a complaint from a user who claims to have been charged $149.99 for an item in the Real-Money Auction House for Diablo III after bidding on an item they say was posted at $0.00. They offer evidence to support this claim as well indications that the bug they encountered is still occurring. On a semi-related note, this thread has the account from a user claiming to have lost a Battle.net balance of $200.00 after changing the region on their account, while this one is from someone who says they called the FBI to report Blizzard for wire fraud, alleging having never received a $49.99 payment for an item they sold. These threads have attracted a lot of attention from users, but so far have received no official "blue" comments from Blizzard. Thanks Joao and Blend Games.

I wonder if they still think their always-on DRM and real money bullshit was worth it? Will they in 6 months plus? I know I'd hate to be A LAWYER working for Blizzard these days.

Fixed. The truth is that they sold six million copies of this game the first week. And millions more since then. That's hundreds of millions in revenue. It seems very unlikely that the cost of the game was anywhere near $100m, so they've made many times their investment back, plus whatever residuals they're making in the RMAH.
